What is 71.5 percent of 2.2 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 2.2 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 2.2 is 100%, so we can write it down as 2.2=100%.
4. We know, that x is 71.5% of the output value, so we can write it down as x=71.5%.
5. Now we have two simple equations:
1) 2.2=100%
2) x=71.5%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
2.2/x=100%/71.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 71.5% of 2.2

2.2/x=100/71.5
(2.2/x)*x=(100/71.5)*x       - we multiply both sides of the equation by x
2.2=1.3986013986*x       - we divide both sides of the equation by (1.3986013986) to get x
2.2/1.3986013986=x
1.573=x
x=1.573

now we have:
71.5% of 2.2=1.573
